MCP Composer

What is MCP Composer?

MCP Composer is a gateway service that centrally manages all your MCP servers. It consolidates multiple MCP servers and opens independent ports with different combinations of servers and tools for each service (such as AI agents or tools) that requires access to MCP servers.

How to use MCP Composer?

After cloning the repository, install dependencies with make install or uv sync. Configure your MCP servers by editing mcp_servers.json and setting environment variables in .env. Run the application with make run or uv run src/main.py. Alternatively, use make run-docker for a Docker deployment.

Key features of MCP Composer

• Dynamic MCP Server Management with on‑the‑fly activation/deactivation.
• Unified Server-Sent Events (SSE) interface for all managed capabilities.
• Multiple dynamic SSE endpoints for different AI agents or tools.
• Independent interface configuration per SSE endpoint.

Use cases of MCP Composer

• Consolidate multiple MCP servers into a single manageable gateway.
• Provide customized tool/ server combinations to different AI agents.
• Dynamically add or remove MCP servers without restarting the gateway.
• Expose MCP capabilities via a unified SSE interface for workflow tools like n8n.
